Cost-effectiveness of Opportunity Charging in Non-electrified Railway Lines Aizpuru, Iosu Olmos Amondarain, Josu Saez de Ibarra Martínez de Contrasta, Andoni Gaztañaga Arantzamendi, Haizea López, Dimas Nieva Fatela, Txomin lithium-ion batteries Costs Sensitivity analysis Conferences Mechanical power transmission Propulsion Rail transportation This paper analyses the cost-effectiveness of deploying opportunity charging points in long-distance non-electrified railway lines, which are driven by battery-based hybrid diesel-electric railway vehicles. A study case based on a real railway line is presented, where potential locations for the charging points are proposed. With the aim of developing a comprehensive sensitivity analysis, for each combination of charging points locations the life cycle costs of different energy management strategies and lithium-ion battery technologies are also compared. Additionally, for each case the optimal size of the powertrain elements is calculated. In order to develop the proposed analysis, a methodology based on an optimization approach is presented. The obtained results demonstrate that deploying opportunity charging points along the route is a feasible solution, as long as appropriate strategies and battery technologies are used. In the best scenario, the life cycle cost of a base case without charging points can be reduced a 4.3%, and the cost of a traditional diesel-electric vehicle a 7.6%. 2022-06-08T13:48:44Z 2022-06-08T13:48:44Z 2021 http://purl.org/coar/resource_type/c_c94f 1938-8756 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=167495 https://hdl.handle.net/20.500.11984/5595 eng © 2021 IEEE IEEE
